It also means that when you have both exported realms in your third (live) realm, then you can get topics auto-linked between the rules and the adventure :-)

That's something that would never be possible across multiple realms.

It's not really a workaround, it's more like how the program is intended to work. You can combine realms/rules/adventures in whole or in part to make your own custom world.

I'm the tech noob here, but I'm curious: wouldn't it be possible to open it a second time in a virtual machine?

Sure, one of them has to be offline, if you're on the same account, but still...

Merging stuff wouldn't be possible with bought content then? Or would it? Well hopefully we see soon :D

Assuming the CM content works like the free stuff LWD has already posted it will merge into other realms just fine. What makes you think it wouldn't?

Just be careful trying to mess with this. It's entirely possible to get your realms out of sync when playing on multiple machines which will result in you needing to re-download the realms from the server or throwing your server version out and using the local.

Can be a real PITA on a slow connection.

I treat my home desktop as my "master" machine. It is the only machine I do imports or create new realms on. My work desktop and laptop are used for editing realms and for running games respectively only.

If you always do something like this and sync whenever you edit you should have no issues.

I need to fix an older realm, but all the mistakes i made with it are still there and impossible to correct. To fix all this properly, i need to just make it new. I'd like to just open it somehow and copy/paste everything.

This was my first realm and i did a lot of learning on it, i'd still like to use the contents, but with all the errors it's just impossible. I'd rather not have to copy/paste into Open Office or Notepad, as that seems like a bit much.

If you can't do an export there really is no option inside RW.

2 computers and a software KVM like InputDirector. This I've done.
Or a virtual machine on one computer that lets you copy/paste into/out of the VM.

The realm-works output tool by Farling may work as well.
